Answer:
Step-by-step explanation:
<h3>Part A</h3>
<u>Solve the equation:</u>
- 6x² + 48x + 120 = 0
- x² + 8x + 20 = 0
- x² + 8x + 16 + 4 = 0
- (x + 4)² + 4 = 0
- (x + 4)² = - 4
The left side is positive and right side is negative so no solution
<h3>Part B</h3>
There is no intercession with the x-axis, the graph of the function is entirely above the x-axis.
It means the diver won't reach the bottom of the lake
Answer:
134.04 cm³ (rounded to tenths)
Step-by-step explanation:
The radius(r) is 4 cm
The height(h) is 8 cm
Using the equation and plugging in the values, you get
Answer:
i think ur in a higher grade then me but im good w/ equations so OoOO0p
Step-by-step explanation:
equation: y = x - 6 + x^2
(6,0) (7,1) (8,4) (9,9)
I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.
A1=2*5^(1-1)
a1=2,
ratio is 5
so correct answers is A
Given:
Radius of small circle = 4 in.
Width of gray border = 2 in.
To find:
The area of the gray border.
Solution:
We have, radius of small circle:
The width of gray border is 2 in. So,t he radius of the larger circle is:
Now, area of gray border is the difference for area of larger circle and smaller circle.
Substituting 
in the above formula, we get
The area of the gray border is 
square inches. Therefore, the correct option is D.
